What smooths an object so it will move easily through a fluid?

If the fluid is air, and assuming that the object is already streamlined and aerodynamic, then polishing or coating its surface with a sticky substance to leave as little jagged spikes at the microscopic level.
If the fluid is water, then possibly coating it with a apolar substance that doesn't interact with water, which is polar would cause it to have less friction and dissipate less energy.
